“…Spirometrical evaluation was done. Additionally, women exposed to biomass fumes were reported to be more likely to suffer from chronic bronchitis and COPD compared with urban women even though the prevalence of smoking was higher among the latter group (8)(9)(10)(11)(12)(13)(14)(15).…”

Comparative study of respiratory symptoms and lung function alterations in patients with chronic obstructive pulmonary disease related to the exposure to wood and tobacco smoke* Estudo comparativo de sintomas respiratórios e função pulmonar em pacientes com doença pulmonar obstrutiva crônica relacionada à exposição à fumaça de lenha e de tabaco AbstractObjective: To describe and analyze clinical symptoms and spirometric alterations of patients with chronic obstructive pulmonary disease (COPD) and history of exposure to wood and tobacco smoke. Methods: We retrospectively evaluated data related to 170 patients distributed into 3 groups: 34 exposed only to wood smoke, 59 patients exposed only to tobacco smoke and 77 patients exposed to both. Results: The groups did not differ significantly in terms of age (p = 0.225) or degree of exposure, considering each type of exposure in isolation or in combination (p = 0.164 and p = 0.220, respectively). Females predominated in the group exposed to wood smoke. There were no differences among the groups regarding respiratory symptoms (p > 0.05), and moderate dyspnea predominated in the three groups (p = 0.141). The group exposed to wood smoke presented higher percentages of forced expiratory volume in one second/forced vital capacity ratio and of forced expiratory volume in one second (p < 0.05). Positive results on bronchodilator testing occurred more frequently in the group exposed to tobacco smoke. The percentage of severe and extremely severe obstruction was significantly higher in the group exposed to tobacco smoke (44.1%) than in that exposed to wood smoke (11.8%; p = 0.006). Conclusions: Respiratory symptoms and pulmonary function alterations consistent with COPD were observed in the groups of patients exposed to wood smoke. However, those alterations were not as significant as the alterations observed in the groups exposed to tobacco smoke. This study emphasizes the importance of prospective studies in evaluating the risk of wood-smoke-related COPD in Brazil, as well as the need for preventive measures in this area.Keywords: Pulmonary disease, chronic obstructive; Smoking; Air pollution, indoor; Smoke.

“…Such high levels of exposures have been implicated in a broad range of adverse health effects. Even though, the mechanisms by which these pollutants affect human health is not entirely known, nevertheless though, exposure to biomass fuel smoke has been associated with several diseases in epidemiological studies (Liu et al, 2007;Regalado et al, 2006). The health related problems resulting from indoor air pollutants are quite pervasive because exposed groups are in proximity to the source.…”

It is widely known that more than half of the world's population use biomass fuels (wood, charcoal, dung) as household energy source, and hence, face significant and diverse range of toxic pollutants. In Sierra Leone, more than 90% of the population relies on biomass fuels. We carried out daytime measurements and observe variation of carbon monoxide (CO) in kitchen and outdoor locations in households that burn wood and charcoal fuels in Western Sierra Leone, during a survey that was conducted in September, 2011. Maximum time average 15 mins, 30 mins, 1 hr and 8 hrs concentrations in indoor and outdoor locations were computed. Mean concentrations decreased in the order, 15 mins to 30 mins to 1 hr and 8 hrs, in the two locations for households that burn wood and charcoal. About 87% and 67% of 8 hrs CO concentrations in kitchens with charcoal and wood stoves were in excess of world health organization (WHO) guideline. Approximately 66% and 63% of 1 hr CO concentrations were not different in the same environments. None of the corresponding outdoor locations had values that are said to be critical to human health. Evidence of greater variation in the maximum time average mean CO concentrations in kitchens with charcoal stoves relative to those using wood was observed. Behavioral patterns in homes burning charcoal coupled with the burning conditions were ascribed to the observed variation. The proportion of the short time and acute CO concentrations in kitchens is a cause for concern for humans from the stand point of improved human health.

The Effect of Biomass Burning on Respiratory Symptoms and Lung Function in Rural Mexican Women

Abstract: Women cooking with biomass fuels have increased respiratory symptoms and a slight average reduction in lung function compared with those cooking with gas.
